Layer 2 Switching

Spanning Tree Protocol (STP)

Standard 802.1d STP support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

Port grouping

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation

VLAN

Support for up to 256 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN

Auto voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

QinQ VLAN

VLANs transparently cross a service provider network while isolating traffic among customers

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)

Protocols for automatically propagating and configuring VLANs in a bridged domain

Head-Of-Line (HOL) blocking

HOL blocking prevention

Loopback detection

Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP.

Automatic Media-Dependent Interface Crossover (MDIX)

Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.

Security

ACLs

Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
Support up to 512 rules

Port security

Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses

IEEE 802.1X (authenticator role)

802.1X: RADIUS authentication; guest VLAN;

RADIUS, TACACS+

Supports RADIUS and TACACS authentication; switch functions as a client

MAC address filtering

Supported

Storm control

Broadcast, multicast, and unknown unicast

DoS protection

DOS attack prevention

STP Bridge Protocol Data Unit (BPDU) Guard

This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port

Spanning Tree Loop Guard

This feature provides additional protection against Layer 2 forwarding loops (STP loops).

Secure Shell (SSH) Protocol

SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported

Secure Sockets Layer (SSL)

SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch

Quality of Service

Priority levels

8 hardware queues

Scheduling

Strict priority and weighted round-robin (WRR)
Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

Class of service

Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)

Rate limiting

Ingress policer, per VLAN and per port
